Answer:

to?

Step-by-step explanation:

Answer:

x = 1/5

Step-by-step explanation:

2x − 4 + 2x = −6x −2

Combine the like terms (2x)

Result:

4  −  4  =  − 6  − 2

Add 4 to both sides:

4 −  4 + 4  = − 6 −  2 + 4

Result:

4 = − 6 + 2

Add 6x to both sides.

4  +  6  = − 6  +  2  +  6

Result:

1 0 = 2

Divide both sides by 10:

1 0 / 1 0 = 2/ 1 0

Result:

x = 1/5

Therefore, x = 1/5 would be your answer.

Answer:

[tex]3 + d \leqslant 3 - d \\ d + d \leqslant 3 - 3 \\ 2d \leqslant 0 \\ d \leqslant 0 \\ thank \: you[/tex]

1) Cancel 3 on both sides

d≤−d

2) Subtract -d from both sides.

d+d≤0

3) Simplify  d+d  to  2d.

2d≤0

4)  Divide both sides by 2.  

d≤0

Answer:

Troy is either 16 or 32.

Step-by-step explanation:

Sorry for not giving the exact answer the question is worded badly..

Answer: 32

Step-by-step explanation:

16 + 16. if you break it down, you can get 8 x 4. so if you count 8, 16, 24, (32) is your answer.

Answer: no

Step-by-step explanation:

an example of a linear equation is x + 1. linear means a straight line. In a linear, the highest exponent on the x opponent is 1. in the equation 3x^2 + 2, the highest exponent on the x opponent is 2 which means this is a quadratic not a linear.

Answer:

m(Au)=45.6 [gr] ; m(Cu)= 10.8 [gr].

Step-by-step explanation:

the masses of gold (Au), copper (Cu) and aluminium (Al) are:

0.76*60=45.6 (gr); 0.18*60=10.8 (gr.) and 0.06*60=3.6 (gr).

Answer:

But what do we have to do ? like add subtract or multiply?  i dont know

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Answer:

You probably already figured it out, but the correct answer is the last one. Subtract 3 from the product of 9 and m

Step-by-step explanation:

Reason for this is 9m is the same as 9 multiplied by m, or the product of 9 and m. You always do multiplication before subtracting or adding, therefore you are subtracting 3 FROM the product of 9 and m

Answer:

-8 -20 or - 8 - 20

correct me if I'm wrong

Answer: -28

Step-by-step explanation: the word "difference" in math means subtraction. so -8-20 is -28

Answer: 5. -64 6. 81 7. 144

Step-by-step explanation:

5. -4 x -4 = +16. +16 x -4 = -64

6. -3 x -3 = 9. 9 x -3 = -27. -27 x -3 = 81

7. kiera + 11 of her friends = 12 people total if 12 people each give fliers to 12 people, its 12 x 12 which is 144

Answer:

Step-by-step explanation:

Each 12 people gives 12 fliers to others. The number of people who gets fliers is:

60%

Step-by-step explanation:

(136 - 85)/85 × 100%

= 51/85 × 100%

= 51/17 × 20%

= 3 × 20%

= 60%

Answer:

i dont know because you didnt give number but is one -17 is so its that

Step-by-step explanation:

Step-by-step explanation:

Given the function, f(x) = -3x + 4, you basically need to choose any input (x-value) and substitute those values into the function.

       f(0) = -3(0) + 4

       f(0) = 0 + 4

       f(0) =  4 [this is the value of your final column, in the f(x)].

   2. f( 1 ) = -3( 1 ) + 4, where the input is x = 1.

       f( 1 ) = -3( 1 ) + 4

       f( 1 ) = -3 + 4

       f( 1 ) =  1 [this is the value of your final column, in the f(x)].

   3. f(2) = -3(2) + 4, where the input is x = 2.

       f(2) = -6 + 4

       f(2) = -2 [this is the value of your final column, in the f(x)].

All you need to do is plot the following points on your graph:

Answer:c two real solutions

Step-by-step explanation:

Answer:

k=4

Step-by-step explanation:

So we have the graphs of f(x) and g(x).

And we know that g(x) is defined as  f(kx), where k is some constant.

First, from the graph we can note two points:

For g(x), we have the point (1,10) and for f(x), we have the point  (4,10).

The associative property is grouping

Step-by-step explanation:

Answer:

The associative property is the rule that includes grouping of numbers.

Step-by-step explanation:

Answer: 1. x=-7 2. m=6

Step-by-step explanation:

1. 5 + x=-2

to get the x by itself, you need to subtract 5 from both sides

5-5 +x = -2-5

there for 0 + x = -7 which means x=-7

2. to get 8m to just m, you need to divide 8m by 8. and what you do to one side of the equation, you need to do to the other. therefore 8m/8=48/8 and 48/8=6. therefore m=6

Answer:

1. 5+x=-2

x=-2-5

x= -7

2. 8m=48

m= 48/8

m= 6
